Thirty-seven eyes of 26 patients with various types of glaucoma underwent trabeculotomy at the Department of Ophthalmology of Tottori University Hospital during the 4 years from February 1986 to January 1990. The cases were followed up for 1 to 46 years, averaging 12.4 months. The mean preoperative intraocular pressure (IOP), 29.4 ± 8.2 mmHg (standard deviation), significantly decreased (P < 0.01) to 17.1 ± 5.1 mmHg, postoperatively. The post-operative IOP was successfully controlled in 30 of the 37 eyes (81.1%). The success rate of postoperative IOP control, analyzed by the life table method of Kaplan-Meier, was estimated to be 78.8% over 43 months. The visual field was improved in 4 of 33 eyes examined (12.1%), unchanged in 26 (78.8%) and deteriorated in 3 (9.1%). As one of the complications during and after surgery, hyphema was observed in all eyes (100%), but neither flat anterior chamber nor choroidal detachment were detected. The results seem to indicate that trabeculotomy is beneficial and effective in the management of various types of glaucoma, with few serious complications.
